So all I want to know is how I can write opcode to a specific memory address.
So I have a adress ... e.g. : 0x323F with the instruction : jmp 0555938

and my Aim is to NOP it with C++.
Before that i already connected to the Process of the game.

Hope someone can help Smile

In an injected DLL, you need only dereference the address after making sure the memory is writable.

In a separate process, you can use OpenProcess and WriteProcessMemory (again, after making sure the memory is writable).

don't forget VirtualQuery(Ex) in both cases

Sorry guys , I need a little more help because its just new to me :/
Sorry sorry :s

I know how to write a Value to memory...
It's like that one :

int newammo = 999;

WriteProcessMemory(hproc,(LPVOID)erg3,&newammo,
sizeof(newammo),0);

but how should i write asm to it ?

Maybe __asm {} ? But which type is it etc...Please give me a short example :S

BYTE NOPBytes[5] = "\x90\x90\x90\x90\x90";
DWORD NOPAddr = 0x00001234;

WriteProcessMemory( hProcessHandle, (LPVOID)NOPAddr, &NOPBytes, 5, NULL );

//Just use bytes instead of asm
